Description

DISPOSITIF ET PROCEDE DE SECURISATION PERSONNELLE D ' UN SUPPORT D ' INFORMATIONDEVICE AND METHOD FOR PERSONALLY SECURING AN INFORMATION MEDIUM
5 La présente invention concerne un dispositif de sécurisation personnelle d'un support d'information et un procédé de réalisation de celui- ci.The present invention relates to a device for personal securing of an information medium and a method of producing it.
Il est connu de pourvoir les supports d'information, par exemple les cartes à puce, d'éléments de sécurisation par exemple d'hologrammes, d'OVI 10 (en anglais Optical Variable Ink : encre optique variable), d'impression en guilloche, etc....It is known to provide information media, for example smart cards, security elements for example holograms, OVI 10 (in English Optical Variable Ink), guilloche printing , etc ....
L'invention se rapporte plus précisément à un dispositif de sécurisation personnelle d'un support d'information comportant une zone d'information personnelle dans le support. 15 II est important en effet de prévoir un élément sécurisé pouvant être mis en place sur le support en fin de fabrication afin de diminuer les risques de vol sur les sites de production. Dans ce cas, la pose de l'élément de sécurisation est effectuée de façon décentralisée.The invention relates more precisely to a device for personal security of an information medium comprising a personal information zone in the medium. It is indeed important to provide a secure element which can be put in place on the support at the end of manufacture in order to reduce the risk of theft on the production sites. In this case, the securing element is installed in a decentralized manner.
Il est connu de réaliser un tel élément de sécurisation personnelle 20 par laser. Une zone avec des cellules en relief est réalisée sur le support et ensuite traitée avec deux lasers simultanément avec des angles d'incidence différents. L'on obtient alors une zone d'information avec des informations différentes selon l'angle d'incidence du support par rapport à l'œil du type appelé couramment « movie card ». 25 Ce type de sécurisation a pour inconvénient d'être particulièrement coûteux.It is known to produce such a personal security element 20 by laser. An area with cells in relief is produced on the support and then treated with two lasers simultaneously with different angles of incidence. One then obtains an information zone with different information depending on the angle of incidence of the support relative to the eye of the type commonly called "movie card". 25 This type of security has the disadvantage of being particularly expensive.
L'invention propose un dispositif de sécurisation personnelle bon marché et particulièrement fiable et, pour ce faire, ce dernier est constituéThe invention provides an inexpensive and particularly reliable personal security device and, to do this, the latter consists
' d'une pluralité de micro-lentilles optiques en un matériau transparent '' of a plurality of optical micro-lenses made of a transparent material
30 disposées sur la zone pour former un motif personnel lisible par un lecteur optique calibré à au moins une caractéristique des micro-lentilles.30 arranged on the area to form a personal pattern readable by an optical reader calibrated to at least one characteristic of micro-lenses.
C€JPIE Kl OOmFî m lî^m Un avantage de ce dispositif est que nécessairement un lecteur optique calibré, c'est-à-dire avec compatibilité entre la lumière du lecteur et les caractéristiques des lentilles, doit être utilisé pour lire le motif. En effet, si un autre lecteur est utilisé, la reconnaissance ne peut être réalisée. Ceci renforce la sécurité du dispositif.C € JPIE Kl OOmFî m lî ^ m An advantage of this device is that necessarily a calibrated optical reader, that is to say with compatibility between the light of the reader and the characteristics of the lenses, must be used to read the pattern. Indeed, if another reader is used, recognition cannot be carried out. This enhances the security of the device.
Un autre avantage de ce dispositif est que sans apport de lumière à l'état non lu, il est totalement transparent et invisible.Another advantage of this device is that without adding light in the unread state, it is completely transparent and invisible.
Egalement, il est possible de modifier les caractéristiques optiques du matériau pour chaque utilisateur ou pour chaque application. Ainsi un lecteur ne lira que le motif personnel d'un seul utilisateur ou d'une seule application.It is also possible to modify the optical characteristics of the material for each user or for each application. Thus a reader will only read the personal motif of a single user or a single application.
Avantageusement, la zone peut être transparente ou réfléchissante. Ceci permet une application autant sur les supports d'information type cartes à puces en matériau transparent en totalité ou partiellement que sur les supports réfléchissants, par exemple revêtus d'une couche d'argent de type support d'hologramme.Advantageously, the zone can be transparent or reflective. This makes it possible to apply it as much on information supports such as smart cards in transparent material in whole or in part as on reflective supports, for example coated with a silver layer of hologram support type.
La caractéristique peut être l'indice de réfraction optique du matériau, le diamètre dess micro-lentilles ou la caractéristique sphérique dess micro-lentilles. Selon un mode de réalisation préféré, le dispositif est revêtu d'une couche de matière transparente d'indice de réfraction différent de celui du matériau.The characteristic may be the optical refractive index of the material, the diameter of the micro-lenses or the spherical characteristic of the micro-lenses. According to a preferred embodiment, the device is coated with a layer of transparent material with a refractive index different from that of the material.
Ceci permet de protéger les micro-lentilles de la détérioration par grattage par exemple. L'invention se rapporte également à un procédé de réalisation d'un tel dispositif, selon lequel les micro-lentilles sont appliquées par jet de gouttes du matériau.This makes it possible to protect the micro-lenses from deterioration by scratching for example. The invention also relates to a method for producing such a device, according to which the micro-lenses are applied by jet of drops of the material.
Le procédé de jet de gouttes comparable au procédé par jet d'encre en matière d'impression a l'avantage d'être peu coûteux, flexible et sans contact. Ce procédé par jet de gouttes est un procédé très largement utilisé pour la personnalisation de documents et l'invention est donc compatible avec une technologie existante faisant office de standard.The drop-jet process comparable to the ink-jet process for printing has the advantage of being inexpensive, flexible and contactless. This drop jet process is a very widely used process for the personalization of documents and the invention is therefore compatible with an existing technology serving as a standard.
Il permet notamment d'effectuer une impression numérique différente pour chaque objet imprimé, ce qui permet une personnalisation de chaque objet.It allows in particular to carry out a different digital printing for each printed object, which allows personalization of each object.
Des caractéristiques différentes des micro-lentilles du dispositif peuvent être obtenues simplement en modifiant le signal électrique de l'injection responsable du volume et de la forme des micro-lentilles. Après projection des gouttes, si besoin, diamètre, forme et caractéristiques optiques des micro-lentilles peuvent être ajustés.Different characteristics of the micro-lenses of the device can be obtained simply by modifying the electrical signal of the injection responsible for the volume and the shape of the micro-lenses. After projection of the drops, if necessary, the diameter, shape and optical characteristics of the micro-lenses can be adjusted.
Ainsi, pour une tête de jet de gouttes et un matériau donné, la modification du signal électrique appliqué au matériau piezo-électrique permettra de faire varier le volume des gouttes et leur vitesse. L'on peut ainsi changer les caractéristiques géométriques des micro-lentilles. Ces caractéristiques géométriques peuvent également être modifiées par variation de la tension de surface du matériau constituant les microlentilles.Thus, for a drop jet head and a given material, the modification of the electrical signal applied to the piezoelectric material will make it possible to vary the volume of the drops and their speed. It is thus possible to change the geometric characteristics of the micro-lenses. These geometric characteristics can also be modified by varying the surface tension of the material constituting the microlenses.
Avantageusement, le motif peut être codé par cryptologie.Advantageously, the pattern can be coded by cryptology.
L'invention est décrite ci-après plus en détail à l'aide de figures ne représentant que des modes de réalisation préférés de l'invention.The invention is described below in more detail using figures representing only preferred embodiments of the invention.
La figure 1 est une vue de face d'un dispositif conforme à l'invention avec un exemple de motif personnel.Figure 1 is a front view of a device according to the invention with an example of personal pattern.
Les figures 2A et 2B sont des vues en coupe schématique d'un dispositif conforme à l'invention lu par un lecteur optique. La figure 3 est une vue en coupe transversale d'un dispositif conforme à l'invention selon une variante de réalisation.Figures 2A and 2B are schematic sectional views of a device according to the invention read by an optical reader. Figure 3 is a cross-sectional view of a device according to the invention according to an alternative embodiment.
La figure 4 est une vue schématique en perspective d'un agencement de réalisation de l'invention par jet de gouttes.Figure 4 is a schematic perspective view of an embodiment of the invention by jet of drops.
Le dispositif de sécurisation personnelle conforme à l'invention représenté sur la figure 1 est constitué d'une pluralité de micro-lentilles optiques 1 en matériau transparent disposées sur une zone 2 d'un support d'information 4, par exemple une carte à puce ou un disque compact, pour former un motif.The personal security device according to the invention shown in Figure 1 consists of a plurality of micro-lenses optics 1 made of transparent material arranged on an area 2 of an information medium 4, for example a smart card or a compact disc, to form a pattern.
Une grande variété de polymères peut être utilisée pour la fabrication des micro-lentilles. Avantageusement, l'on utilisera des résines liquides polymérisables aux UV et d'indice de réfraction calibré. Par exemple les produits commercialisés par la société ABLESTIK nommés « LUXTRACKA wide variety of polymers can be used for the manufacture of micro-lenses. Advantageously, use will be made of liquid resins which can be polymerized by UV rays and with a calibrated refractive index. For example the products marketed by the ABLESTIK company called “LUXTRACK
4041 » ou « LUSTRACK 4037 » sont utilisés.4041 "or" LUSTRACK 4037 "are used.
Ce motif est la donnée personnelle de l'utilisateur du support. Dans ce motif, chaque micro-lentille 1 forme un point. II peut être de fantaisie constitué d'une chaîne de points comme ici représenté ou constitué par un code barres.This reason is the personal data of the support user. In this pattern, each microlens 1 forms a point. It can be fancy consisting of a chain of points as shown here or consisting of a bar code.
La zone 2 est transparente.Zone 2 is transparent.
Ce motif est lisible par un lecteur optique 3A calibré à au moins une caractéristique des micro-lentilles 1 et disposé d'un côté du support 4, du côté de la face portant les micro-lentilles 1, comme représenté sur la figureThis pattern can be read by an optical reader 3A calibrated to at least one characteristic of the micro-lenses 1 and arranged on one side of the support 4, on the side of the face carrying the micro-lenses 1, as shown in the figure.
2A. Le motif est alors visible du côté 6A du support 4 opposé à la face portant les micro-lentilles 1.2A. The pattern is then visible on the side 6A of the support 4 opposite the face carrying the microlenses 1.
Cette caractéristique peut être l'indice de réfraction optique du matériau, le diamètre dess micro-lentilles ou la caractéristique spherique dess micro-lentilles.This characteristic can be the optical refractive index of the material, the diameter of micro-lenses or the spherical characteristic of micro-lenses.
Selon une variante, le lecteur peut être disposé sur la face opposé de la zone transparente du support et le motif être lu du côté de la zone portant les micro-lentilles. Le lecteur optique est constitué de façon classique d'une pluralité de diodes électroluminiscentes.According to a variant, the reader can be arranged on the opposite face of the transparent area of the support and the pattern can be read from the side of the area carrying the microlenses. The optical reader conventionally consists of a plurality of light-emitting diodes.
Afin de protéger les micro-lentilles de la détérioration par grattage par exemple, le dispositif peut être revêtu d'une couche 5 de matière transparente d'indice de réfraction différent de celui du matériau, comme représenté sur la figure 3. Cette couche de protection est avantageusement un vernis déposé par tout type de technique d'impression. Tout vernis peut être utilisé à condition d'avoir un indice de réfraction très différent de celui du matériau des micro-lentilles. Selon le procédé de réalisation conforme à l'invention, les microlentilles 1 sont appliquées par jet de gouttes du matériau comme représenté sur la figure 4. Une barre d'injection 7 balaie à une certaine vitesse la zone 2 où un motif de micro-lentilles 1 doit être réalisé et par signal électrique, jette des gouttes de matériau avec un certain volume et une certaine vitesse. La taille des gouttes est de l'ordre de 20 à 100 micromètres de diamètre, de préférence 40 à 80 micromètres.In order to protect the micro-lenses from deterioration by scratching, for example, the device can be coated with a layer 5 of transparent material with a refractive index different from that of the material, as shown in FIG. 3. This protective layer is advantageously a varnish deposited by any type of printing technique. Any varnish can be used provided that it has a refractive index very different from that of the material of micro-lenses. According to the production method according to the invention, the microlenses 1 are applied by jet of drops of the material as shown in FIG. 4. An injection bar 7 sweeps at a certain speed the area 2 where a pattern of microlenses 1 must be carried out and by electrical signal, throws drops of material with a certain volume and a certain speed. The size of the drops is of the order of 20 to 100 micrometers in diameter, preferably 40 to 80 micrometers.
Avantageusement, le motif peut être codé par cryptologie La zone 2 du support peut également être réfléchissante. Dans ce cas représenté sur la figure 2B, le lecteur optique 3B est disposé du côté de la face portant les micro-lentilles 1. Dans ce cas, on positionne le lecteur optique 3B de telle sorte que son faiseau optique soit décentré par rapport à l'axe de symétrie des micro-lentilles 1 et le motif est visible en un point 6B symétriquement décalé par rapport à cet axe de symétrie.Advantageously, the pattern can be coded by cryptology. Zone 2 of the support can also be reflective. In this case shown in FIG. 2B, the optical reader 3B is disposed on the side of the face carrying the micro-lenses 1. In this case, the optical reader 3B is positioned so that its optical beam is off-center with respect to the 'axis of symmetry of the microlenses 1 and the pattern is visible at a point 6B symmetrically offset with respect to this axis of symmetry.
Typiquement, dans le cas d'un disque compact portant des micro- lentilles, le lecteur peut être constitué par le laser utilisé pour lire le contenu du disque compact lui-même. Il n'est dans ce cas pas nécessaire de prévoir un lecteur spécifique pour lire le motif formé par les micro-lentilles.Typically, in the case of a compact disc carrying microlenses, the reader may consist of the laser used to read the content of the compact disc itself. In this case, it is not necessary to provide a specific reader to read the pattern formed by the micro-lenses.
Le lecteur a pour fonction de donner à son utilisateur ou à un dispositif d'identification une indication relative à l'authenticité . du support d'information. A titre d'exemple, dans le cas d'un disque compact, le lecteur comporte un dispositif d'authentification destiné à vérifier que le disque est bien un disque original et non une copie. Cette authentification peut consister à vérifier que le motif correspond bien à un motif attendu, par exemple à un motif standard caractérisant les disques originaux provenant d'éditeurs, ou à un motif correspondant à des informations lues parmi les informations contenues dans le support. Dans ce second cas, il peut donc s'agir d'une comparaison du motif optique avec des informations numériques, par exemple noyées parmi celles figurant dans le support.The function of the reader is to give its user or an identification device an indication relating to authenticity . information carrier. By way of example, in the case of a compact disc, the reader includes an authentication device intended to verify that the disc is indeed an original disc and not a copy. This authentication can consist in verifying that the pattern corresponds indeed to an expected pattern, for example to a standard pattern characterizing the original discs coming from publishers, or to a pattern corresponding to information read among the information contained in the support. In this second case, it can therefore be a comparison of the optical pattern with digital information, for example embedded among those appearing in the support.
Dans le cas d'une carte à puce, il est possible d'authentifier la carte en comparant les informations optiques avec des informations lues dans la puce de la carte. Il est également possible, par exemple dans le cas d'un contrôle d'accès, de comparer les informations optiques avec un code entré manuellement par l'utilisateur sur un clavier à touches coopérant avec le lecteur optique. Les informations optiques peuvent donc être assimilées à un code- barre et les applications des codes-barres font partie intégrante de l'invention décrite ci-dessus.In the case of a smart card, it is possible to authenticate the card by comparing the optical information with information read from the card chip. It is also possible, for example in the case of access control, to compare the optical information with a code entered manually by the user on a keyboard with keys cooperating with the optical reader. The optical information can therefore be assimilated to a bar code and the applications of bar codes are an integral part of the invention described above.
D'autres applications à la portée de l'homme du métier sont possibles. Other applications within the reach of those skilled in the art are possible.
